is it a binary-only library ?  if it's open source, encoding the arch in the 
name is a dumb convention that only causes misery.

if you're statically linking against it, then add a configure library test.  
if you're dynamically loading it, then simply try them both.  the host ldso 
should prevent loading of non-compatible ELFs.
